Girlfriend experiences bleeding during/after sex... ONLY when we don t use condoms. Why? When we use a condom she s fine. No blood . The bleeding doesn t last long at all either. A couple of months ago, we were both diagnosed with chlamydia . We followed all advised precautions so as not to repeat infection. Once we were both cleared, nearly a month and a half after the infection, treatment, and retesting, we resumed unprotected sex. At which she point, she resumed post coital bleeding. There s no discomfort or pain, just completely freaked out that something might be wrong... Both of us. Doctors and nurses we ve both seen seem to believe it s tied to her birth control , which is fine. What s troubling is the fact that this only happens when we DON T wear CONDOMS. Again, there s no bleeding the next day or anything. Not looking for a diagnosis, just looking for some intelligent ideas as to why this might be occurring, because at this point, invariably, we will be seeing them again. Thanks!
